At the top of the reitical shaft 58 15 secured a cam 75 provided with a sinuonw groove 0. llngaging in the said groove is a roller $1 mounted at the end of a lever which leveris secured to a shalt 83 mounted longitudinally along the top of the frame;

work. Secured to the sha ft 83 are a series-of levers 81 each having a forked inner end 85.

At one end of the framework is a pulley R0 driving a rear longitudinal sna it 87. I

Upon the shaft 87 are a series of bevel wheels 88 each provided with a clutch 89 of anysuit able' character. Engaging with each bevel wheel 88 is a bevel wheel 90 secured to the outer end of a sha f1; i 1attachcd to the inner end of which is a bevel wheel 92. En gaging with each of the bevel wheels. 92 is a bevelwheel 93 secured i'utermediatcly upon a hollow vertical spihdle 9%.

Attached to the bottom of each spindle 91 is a seaming head 95 upstanding above which are two pairs of opposite lugs 06 each pair carrying a pivot pin 97. Mounted on each of the pivot pins 97 is an intcrmedi ately pivoted lever 98 in the bottom of which is an incut or recess 99. In the said seaminghead 05 are two opposite slideways 100 in each of which is a major slide 101. Each major slide carries a cross pin 1.02 accommodated by the incnt 99 of the lever 98 aforesaid. In each major slide 101 is a minor slide 103, controlled by an adjusting screw 101 and carrying a seaming roller 10-3.

Firmly mounted at the top of the lever 98 first actuated, as hereinafter enplained, is a roller 10$. In the top of the lever 98 last, actuated, as hereinafter explained, a slideway 106 in which is a slide 107 carrying "a roller 108. 'Behind the slide 107 in the slideway 106is an elastic cushion 109 the' tension of which is adjusted by an adjusting slide 110 and a screw 111 (Fig. 23).

Sliding upon each hollow spindle 91 is a sleeve 112 each'provided at the top with a circumferential groove or recess 113. At one side of said sleeve is an inwardly inclined surface 114 opposite which, at the other sideof said sleeve, is an outwardly inclined surface 115.

Within each hollow spindle 94 is a hollow guide and chuck carrier 116 having attachc d to its bottom a chuck 117. Con trall v dis-ported in the lower surface ofthc chuck 117 is a recess 11S. Around the said lowcrsurface is a circumferential 'millcd flange 110. Within the hollow guide and chuck carrier 116 a disengaging rod 120 having at its bottom a disk 121 and at, its

5 top a recessed or grooved collar 122. iblc 5 i-Utached to each seaming dish-preferably (1irrum'tcrc:itially between the slides 101, are two devices for (lat-toning, reforming, or correctly shaping the flanges to be double sean'u-r'd. These are hereinafter called flange reformers 123 and each is provided with a foot 12% bearing upon the upper face of the circumferential llnnge 119 of the chuck 117 (Fig, 18"). Or reforming rollers 121 may be used to operate in the same manner as the feet 121. I

Attached by a connecting rod 125 and pivot pin 1'36 to each of the levers GS is a slide This consists of two side members 127 united by a bridge piece 128 (Fig. 17). Upstanding above each side member are a series of pivot pins 129 upon. each of which moves an arm 1 30. -'l'he arms of each member 127 correspond in situation forming working pairs. Each arm is controlled by a spring 131 one end of which is attached to the said arm the spring then passing around the pivot pin 129 and being attached at its other end to the SldQ1I'lBll'lliC-l. 127. The springs 131- of the second pair of arms are stronger than their fellows. Upstanding above each side member are also a series of stops 132 one for each arm 130. ()nl: standing from each arm is a limiting protuberance 13 1 each of which engagcswith one of the said stops The cycle of operations in this machine is as follows: The onus with the ends poised thereon or partially crimped' thereto are placed upon the feed belt 12 and traveling" therewith come into contact either with inner deflecting guides 14 or outer deflecting guide; 16 dependent upon the position occn pied upon the belt whether adjacent to the inner side pieces 8 or outer side pieces 10.

if coming into contact with an inner defiecting guide 1 1 it is plain from the conformation of the guide that the can will be re 'tained thereby and that any canwhich may be immediately following on will pass-that guide and be retained by the next. Should a can come into contact withan outer dc fleeting guide 16 the conformation of the same is such, as shown as to deflect the can toward the inner guides. Should all, the inner guides 14 be retaining cans simultaneously the cans then being fed by the belt12 willsimply pass by each inner deflecting.

guide 14 successively being projected hack between the guides by the outer deflecting guides 16. l Vhen the combined'inner and lifting of the lifting rods 18 by the levers outer end deflecting guide is reached the cans which cannot be accounnmlatcd by the l inner guides U are simply deflected on to the return belt 13 and cumin; into contact with the guide p tion 13" ]):l through the opening 11 and are rc-fed. Should a block or interruption of cans momentarily occur a at any of the inner deflecting guides 11 it is 3 plain that the succeeding cans being fed will simply pass through the openings 11. between the outer side pieces 10 and be returned by the return belt 13. Thus the cans can never receive injury and the feed continuous and need not be stopped. Each can when retained by an inner deflecting guide 14 is prevented from passingi freely through its openin 9 by the plate springs 9. The can is t en half on and half off the feed belt 12. Each can is fully carried through the opening 9 and poised upon its can rest or cross 20 by its relative slide, the end arms 130 each time the slide recedes, carrying a can as far as its cross 20. This will be hereinafter more fully gx plained. Each segmental head 53, by the rotation of the shaft 28, small cams 43, and

45, now has its four segments 54 ipassed through the passageway 19, the spaces 55 between the'segments 54 accommodating the cross 20. Each can is thus lifted by its respective'head 53 from the cross 20 and centrally poisedupon' said head by the inclined inner upper faces 56 thereof. When the can is elevated its end or disk 205 comes into contact with the chuck 117 the milled circumferential flange 119 of which is then seated comfortably within the depression 206 of said disk. The flange of the chuck being milled revents the can turning. Should the can liolders 54 be employed it is clear that as the head 53 is elevated the protuberances 5P come into contact with the set screws 7". The milled gripping edges 54* are thus pressed firmly into contact with the can and effectually prevent it turning even in very exceptional circumstances. The foot 1240f each flange reformer 123, or the reforming rollers 121", now )ass rapidly over the top of the flange 207 o the disk 205 and positively flatten the same and the flange 204 of the can body to right angles with the said body. It does not need explaining that each of the searningheads 95 carrying the reformers 123 receives its rotary movement from the pulley 86, shaft 87, bevelwheels and hollow vertical spindle 94 and that the chuck 117 does not rotate with the seaming head 95 and hollow spindle 94.

It may be necessary to point out, thou'gln, that it sometimes happens that although all cans are thought to be of a uni-form height this is not so and slight variations occur. To overcome this difficulty the cushions 52 absorbed by the cushion 52 and vice versa.

'rod 120 caused by the aet'uatiohiofeirch-re are inserted in the female members 51 and it is apparent that upon the male members .30 being depressed on said cushions by the lifting rods 48 the difference in height is At the same time that the small cams 43 are causing the elevation of the heads 53 the relatively large cam 33 by its sinuous ,groove 34, roller 35, lower intermediately pivoted lever 30, connecting rod and upper intermediately pivoted lever 10, the forked end 42 of which engages with the groove or recess 113, is causing the sliding sleeve 112 to move upon the hollow vertical spindle.

As the sleeve 112 descends the inwardly inclined surface 114 comes into contact with the adjacent roller 10S and by the intermediately pivoted lever 98 moves the corresponding major slide 101 carrying its seaming roller 105 inwardly and into engagement with the can. As the sleeve 112 ascends the outwardly inclined surface 115 'comes-into contact with its adjacent roller 108 and by the intermediately pivoted lever 98 moves the corresponding major slide 101 carrying its seaming roller 105 inwardly into engagement with the can also. The can end is seamed to the can body by the rollers 105 as is usual. Adjustment of the rollers 105 is effected by the adjusting screws 104 controlling the minor slides 103 to'which the rollers are attached. Should there be a defect in the flanges of the can body or the can end. the elastic cushion 109 provides for seaming being properly etfected as the final pressure by its influence although firm is gentle and prevents the double seam splitting. This particularly applies to the double thickness of metal in the can body owing to the. vertical seam 203.

\Vhen double seaming has been effected and the heads 53 by the conformation of the small cams 43 commence to recede, the disk 121 upon the lower .end of the disengaging rod 120 resses upon the end of the can and positively and effectually disengages it from the seaming head 95. At the end of the seaming operation the seaming rollers 105 will be disengaged from the can by cen trifugal action; although springs might be en'iployed to positively retract the seaming rollers if desired; but said rollers will be moved outward and retained in their outermost. position by centrifugal force and until forcibly moved inward by the action of the surfaces or cams 114, 115. :The disengaging mover-neat is effected by d'epressionof the spective lever 84 wbichjisin;turniefi'ectedsf,

from the shaft 83 in tuw actuated bysthe sa id lever by following I the na es my of the* carri 79. The cam =79 it is' lai srotated by the vertical shaft whwhis driven by bevel wheels from the longitudinal shaft 28..

lever 82 the roller 81jofwhich operatcS the v the arms 130 moving freely pass the can but assuming ti ic ns As the heads 3 recede the cans with their end double seamed thereto are once more dep ..i d each. upon its can rest or cross 20. The slides now remove the cans. This is cilee ed by the roller 61 following the sinuous cove of the box cam 59 and actuating the lv- 'l crank leverwhich by the link and liver 66 operates the rocking shaft 67 and levers 68. Each lever 68 is byits respecti c connecting rod 125 and pivot pill 126 engaged with its relative slide. As each slide is moved, 'for example, toward the openings 9 its two side members 127 pass each side of the can then upon the cross 20 outwardly to eir inward po- =iiions when past it on account ofrfythe springs 131. The inward movement is ited by the stops 132 andprotuherances 133.

its the slide recedes by the action of the mechanism abovemontioned it is clear that the arms 130 bearing up behind the can remove it from the cross 20. The slides may deliver the cans to a chute conveyor or any other device for removing them from the machine. 7 i

The first pair of arms of the slide, when a van is being removed from a cross 20, have already engaged the can within the corresponding inner deflecting guide 1 and at the same time that the can is bein removed from-its cross the said first pair 0 arms are carrying their can toward the said cross 20. When the cross is reached the slide again moves toward the opening 9 the first pair of arms 130 engaging a new can'and another pair ofurms 130 bearing behind the can on the cross. The can on the cross is now elevated by the relative segmental head 53 and during such elevation and until the can is :wain deposited on the cross the slide, by the sinuosity of the. groove 60 of the cam 59, remains stationary; It is thus plain that during double seaming a pair of arms 130 are hearingagainst the can being seamed,

soon as the seamed'can is deposited on its cross the slide removes it and placesanother can in position as already explained. The second pair of arms 130 having the stronger springs 131'? prevent the possibility of aran being inadvertently moved toward its cross by any unforeseen circumstance such as the accidental pressure of cans bein fed. (3

fihould any obstruction occur to the slide such an inadvertent accumulation'of cans the said slide upon reaching the same and encountering unnatural opposed pressure is automatically thrown out of gear as'long the obstruction exists thereby preventing a can or'cans being injured. It automatically re-comlnences its operations however when the obstruction is removed. This is clfected by the pin 76 the point or nose of which is held within the pin hole 69 of the "the collar 70 which actuates it.

Each collar 7 O is actuated by the rocking shaft through the agency of the pivoted key 74. By having the key 74 pivoted and spring controlled as shown, by depressing the key 14 and moving any one collar 70 along the shaft out of engagement with its corresponding lever (38 any individual slide ma be out out without interfering with the action of the remainder. The necessity of this is obvious. as also is the use of the clutches 89 for disengaging the seaming heads individually and the clutches 47 for disengaging the elevating heads 53 individually. i
